SMOKING PIPE Filed Feb. 6, 1936 Inventor mad Atto'meys Patented May 25, I937 UITED STATES PIIATENT o Flc 2 Claims.

from mixing with the saliva and the moisture and 5 saliva is prevented from entering the smokers mouth. Briefly the invention consists in providing for the trapping of the saliva and for the passage of the smoke from the bowl of the pipe to the smokers mouth in such a manner as to be free of all saliva and moisture thus tending to the greater enjoyment of pipe smoking.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawing wherein:

Figure 1 is a longitudinal sectional view through a pipe, on an enlarged scale and illustrating the application of the invention, and

Figure 2 is a sectional view taken substantially on the line 2-2 of Figure 1.

Referring to the drawing by reference numerals it will be seen that I have illustrated the invention as applied to a pipe consisting of a bowl 5 having an integral stem 6, the free end of which is equipped with a band l2 and abuts one end of a mouth piece 1. The bowl 5 is connected with the stem 6 through the medium of a passage 8 and the bore of the stem 6 is of a diameter materially greater than the diameter of a conventional pipe stem.

The mouth piece 1 is provided with a smoke passage l0 and at the end thereof where the mouth piece 1 abuts the stem 6 said mouth piece 1 is provided with a relatively large bore ll.

Accommodated within the bores of stem 6 and mouth piece I, and overlapping the joint between the stem 6 and mouth piece I are a smoke tube l3 and a saliva tube or trap M. 'The tubes l3 and I4 terminate short of the inner ends of the bores whereby to provide at the inner end of the bore of stem 6 a nicotine trap 9, and at the inner end of the bore II a, chamber H5.

The tubes 13 and I4 are of such a shape in cross section, and as clearly shown in .the drawing as to fit conformably within the bores of stem 6 and mouth piece 1, tube l4 being relatively large and having a curved wall as shown and a flat wall Ma which is the top wall of the tube.

Tube I3, is complemental to tube 14 and is sub-2 stantially segmental in shape, having a curved peripheral wall and a bottom fiat wall l3a which rests flatly on the wall him of the tube l4.

Each of the tubes is open at its respective opposite ends, and at the end thereof facing the chamber 9 tube I4 is provided with a knob equipped,

removable plug l5 that serves to close said end of the tube I4.

While I have illustrated tubes [3 and I4 as being constructed separately from one another it is understood that a single tube may be employed, and where a single tube is employed, the same will be cylindrical in cross section and will be provided with a suitable partition for dividing the single tube into a relatively large compartment having the same function as tube l4, and a relatively smaller compartment having the same function as tube 13.

In actual practice the smoke from the bowl 5 passes through the passage 8 into the nicotine trap 9. From the trap 9 the smoke passes through the tube l3 into the chamber 16, and from the chamber l6 through the smoke passage ill of the stem to the smokers mouth. Any saliva from the smokers mouth will pass inwardly through the passage [0 into the chamber l6, and from the chamber l6 into the tube 14 where it is trapped, and not permitted to enter the nicotine trap 9 and consequently not permitted to mix with the smoke that passes through the trap 9 from the bowl 5 to the tube l3.

The chamber I6 is large enough so that any moisture that might form in the smoke tube 13 and be sucked into the chamber l6 by the smoke, will not jump the chamber l6 and pass into the smoke channel H] but rather, such moisture will fall into the chamber I6 and carried by the saliva from the chamber 16 into the saliva trap tube 54.

Thus it Will be seen that the smoke drawn into the smokers mouth from the bowl 5 will be free of all moisture and saliva, thus insuring to the smoker a clean and more refreshing smoke than is obtained where the saliva and nicotine and other such moisture are permitted to mingle with the smoke as it passes from the channel Ill of the mouth piece 1 into the smokers mouth.

When it is desired to clean the tubes l3 and [4, the mouth piece 1 may be readily separated from the stem 6, whereby access is then easily had to the tubes l3 and I4, and thus permitting these tubes to be readily removed and cleaned. 5

The parts may be reassembled, as is apparent, in a quick and eflicient manner.

Having thus described the invention, what is claimed as new is: a

1. A smokers pipe including a bowl having a hollow stem with a restricted smoke passage and a mouth piece abutting at one end with one end of the stem, a chamber at the connected ends of the stem and mouth piece and a pair of segmental cylindrical tubes disposed alongside of one another, said tubes collectively forming a completed cylinder and snugly fitted within the respective ends of the stem and mouthpiece, said tubes at one end terminating short of the bowl to provide within the stem adjacent to the bowl a nicotine trap, and at the ends thereof remote from the bowl said tubes terminating short of the restricted smoke passage of the stem to provide a chamber connecting said tubes and the smoke passage, and a plug removably disposed in the first named end of one of said tubes.

2. In a smokers pipe, a bowl having a stem and outwardly of the tube having communication 10 with the ends of the chamber.
